In restoring-faith-in-humanity news, a school in Brazil called the Red Balloon English language school has been targeting bad grammar by citing offending tweets from the likes of Lady Gaga, Rihanna and Justin Bieber.

As The Guardian reports, Red Balloon has taken a rather contemporary approach to teaching kids how to use grammatical English, by enlisting them and sending them out on Twitter as so-called ‘Celeb Grammar Cops.’

Here is an example of the Grammar Cops in action:

Hi @rihanna! I love your songs. My name is Carolina. I’m 11 years old. It’s not to she, it’s to her. bye bye . pic.twitter.com/JR8GtPW156

And that’s just about the greatest thing ever.
